It is similar to Photographic Memory but the difference is that this only works when you see something Erotic/Sexual. I.E. your girlfriend in the new set of panties you got her. Or seeing that man you want to have and just saw him naked.

Alex: So how did your girl like the new stuff you got her?
Les: She loved it! She did a little modeling show for me. My Sexualgraphic memory kicked in and that’s all I can see now when I close my eyes.
Alex: Nice!
